在Delphi中执行HTTPS POST请求的最简单方法是什么?我在发出HTTP POST请求时遇到问题,但是如何使用SSL呢?我已经google了一下,并没有找到任何能够解释得很好的东西。
这是我尝试过的代码:
procedure TForm1.FormCreate(Sender: TObject);
var
responseXML:TMemoryStream;
responseFromServer:string;
begin
responseXML := TMemoryStream.Create;
IdSSLIOHandlerSocketOpenSSL1 := TIdSSLIOHandlerSocketOpenSSL.Create(self);
with idSSLIOHandlerSocketOpenSSL1 do
begin
SSLOptions.Method := sslvSSLv2;
SSLOptions.Mode := sslmUnassigned;
SSLOptions.VerifyMode := [];
SSLOptions.VerifyDepth := 0;
host := '';
end;
IdHTTP1 := TIdHTTP.Create(Self);
with IdHTTP1 do
begin
IOHandler := IdSSLIOHandlerSocketOpenSSL1;
AllowCookies := True;
ProxyParams.BasicAuthentication := False;
ProxyParams.ProxyPort := 0;
Request.ContentLength := -1;
Request.ContentRangeEnd := 0;
Request.ContentRangeStart := 0;
Request.Accept := 'text/html, */*';
Request.BasicAuthentication := False;
Request.UserAgent := 'Mozilla/3.0 (compatible; Indy Library)';
HTTPOptions := [hoForceEncodeParams];
end;
responsefromserver := IdHTTP1.Post('https://.../','name1=value1&name2=value2&....');
end;
当我尝试运行它时,我收到以下错误:
Project myProject.exe raised exception class EFOpenError with message 'Cannot open file "C:\...\Projects\Debug\Win32\name1=value1name2=value2 The system cannot find the file specified'.
我不明白。我发送参数,虽然错误听起来像我会发送文件。
此外,我在myProject.exe文件夹中包含了libeay32.dll和ssleay32.dll。

你没有指定你的Delphi版本或indy版本,但是在使用捆绑的Indy与Delphi 2009和HTTPS之前我遇到了一些问题,当我从indy svn获得最新的源代码时,问题就解决了。< / p>

var S: TStringList;
M: TStream;
begin
S := TStringList.Create;
M := TMemoryStream.Create;
try
S.Values['Email'] := 'your google account';
S.Values['Passwd'] := 'your password';
S.Values['source'] := 'estream-sqloffice-1.1.1.1';
S.Values['service'] := 'cl';
IdHTTP1.IOHandler := IdSSLIOHandlerSocketOpenSSL1;
IdHTTP1.Request.ContentType := 'application/x-www-form-urlencoded';
IdHTTP1.Post('https://www.google.com/accounts/ClientLogin', S, M);
Memo1.Lines.Add(Format('Response Code: %d', [IdHTTP1.ResponseCode]));
Memo1.Lines.Add(Format('Response Text: %s', [IdHTTP1.ResponseText]));
M.Position := 0;
S.LoadFromStream(M);
Memo1.Lines.AddStrings(S);
finally
S.Free;
M.Free;
end;

Indy的另一个替代方案是Synapse。
这个类库提供了对帖子的完全控制,但也提供了一个简单的单线程帖子方法:
function HttpPostURL(const URL, URLData: string; const Data: TStream): Boolean;
